Patent CA-2486867-A1 (CA)
Inventor: AKTIK CETIN
IPC: C23C16/32
Filed: 2003-05-23
Abstract: The process of Polymer Assisted Chemical Vapor Deposition (PACVD) and the semiconductor, dielectric, passivating or protecting thin films produced by the process are described. A semiconductor thin film of amorphous silicon carbide is obtained through vapor deposition following desublimation of pyrolysis products of polymeric precursors (19) in inert or active atmosphere (60). PA-CVD allows one or multi-layers compositions, microstructures and thicknesses to be deposited on a wide variety of substrates (6). The deposited thin film from desublimation is an n-type semiconductor with a low donor concentration in the range of 1014- 1017cm-3. Many devices can be fabricated by the PA-CVD method of the invention such as; solar cells; light-emitting diodes; transistors; photothyristors, as well as integrated monolithic devices on a single chip. Using this novel technique, high deposition rates can be obtained from chemically synchronized Si-C bonds redistribution in organo-polysilanes in the temperature range of about 200 - 450 ~C.

Title: Speech dialogue systems with repair facility
Inventor: MCINNES FERGUS ROBERT
IPC: H04M3/42
Filed: 2003-06-20
Abstract: The system has a speech recogniser (2) for recognising speech from a user an d a synthesiser (6) for replying to him and engages in a dialogue with the object of enabling the user to convey to the system a piece of information such as a telephone number. The system builds up the number in a buffer (10) . Each time it receives a string of digits, it reads it back for confirmation. When a number (or part of one) is read back, it is divided into "chunks" according to certain criteria: the positions of these divisions can be recorded to be taken into account in later processing. Responses are compare d with the current buffer contents to determine whether they it should be interpreted as a correction, partial correction or pure continuation of the existing contents. Positions in the buffer at which pure continuations are entered are marked, to allow a "final repair" process in which, if the final result fails to match some criterion of acceptability (e.g. length) the mark ed positions can be reexamined to determine whether interpretation instead as correction or partial correction would meet the criterion. Algorithms are described for comparing new input with digits already received, to decide ho w it is to be interpreted.

IPC: G06F9/44
Filed: 2001-10-31
Abstract: A method and apparatus for the data-driven synchronous parallel processing of digital data, which temporally separates the processes of instructions distributions and data requests from the process of actual data processing. The method includes the steps of: dividing the stream of digital data into data packets, consecutively distributing instructions to data processing units before their execution, consecutively synchronously processing data packets by multiple data processing units processing in parallel, and synchronization of parallel multiple data processing units by data tokens attached to the data packets. In the preferred embodiment the method comprises one or more of the steps of storing instructions inside the data processing units, requesting data before the start of data processing, storing records for requested data packets, associating received data with the records of data requests, attaching to each data packet a validity signal (data token) indicating the validity or non-validity of the received data for processing, and extension of data buffers coupled to the data processing units into elastic data buffers capable of absorbing variations in the data rate. The method provides a data-driven synchronization of parallel synchronous multiprocessor system and a substantially non-stalling flow of digital data through a digital data processor, and the apparatus includes a programmable apparatus which implements the method. In the preferred embodiment a data buffer is provided between adjacent data handling units, and the invention manipulates the timing of the buffer's emptiness and fullness signals, processing each data packet coming into buffer in accordance with its validity signal (data token), and associating a validity signal (data token) with the data packet sent out from buffer.

Patent CA-2526032-A1 (CA)
Inventor: WOBBEN ALOYS
IPC: F03D11/00
Filed: 2004-05-14
Abstract: La présente invention concerne un procédé de fonctionnement d'une éolienne, qui consiste à enregistrer les valeurs de paramètres de fonctionnement prédéfinis au moyen de capteurs appropriés, à enregistrer au moins une condition limite prédéfinie et à comparer les valeurs enregistrées avec des valeurs mémorisées des paramètres de fonctionnement. Cette invention concerne également une éolienne permettant la mise en oeuvre dudit procédé. L'objectif de cette invention est de pouvoir adapter le fonctionnement d'une éolienne à des modifications. A cet effet, selon le procédé susmentionné, lorsque les valeurs de paramètres enregistrées diffèrent des valeurs de paramètres mémorisées et en fonction de la condition limite, soit les valeurs de paramètres mémorisées sont adaptées aux valeurs de paramètres enregistrées, soit le fonctionnement de l'éolienne est influencé en fonction des valeurs de paramètres enregistrées. Cette invention repose sur le fait que, d'un point de vue pragmatique, même le givrage d'une pale de rotor entraîne une modification (temporaire, attribuable aux conditions météorologiques) de la forme de la pale. Pour cette raison, un givrage des pales d'une éolienne entraîne toujours une modification du profil aérodynamique et nuit, ainsi, au rendement de l'éolienne. Toutefois, des divergences des pales de rotor par rapport à la forme optimale prédéfinie résultant de la fabrication et des divergences par rapport à ladite forme résultant de l'encrassement graduel des pales de rotor en cours de fonctionnement induisent également des différences de rendement.
